The aim of this project is to apply GPS, GIS and 3G wireless transmission technology ontrawling fishery surveys in the southwest coast of Taiwan. The survey includes biological sampling, hydrology and satellite remote sensing image data to build vessel tracks, catch, fish biology, and hydrology database in thetrawling fisheries information system of southwestcoast of Taiwan. The system then uses spatial overlay and geostatistical analysis techniques to construct integrated trawling fisheries information on spatial and temporal distribution. This will help fisher, policy makers and related researchers to have whole information.
This year, ten fishing boats were selected from two fishing ports. Each boat was installed a GPS recorder with 3G device. Transmission and receivers were built around the ports. There were 8,000 trawling operation with over 50,000 catch by species. Data of Gonad stage with body length and weight were over 4,000 records in 12 important species.
